Abstract:
Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering (SERS) is a surface-sensitive technique that enhances Raman scattering of molecules adsorbed on rough metal surfaces [1]. It is a powerful vibrational spectroscopy technique that allows for highly sensitive detection of low concentration analytes through the amplification of electromagnetic fields generated by the excitation of localized surface plasmons [2]. SERS has progressed from studies of model systems on roughened electrodes to highly sophisticated studies, such as single molecule spectroscopy [3]. In this talk I am going to give an anecdote of Conventional Raman Spectroscopy and how the intensity of the Raman signal is being amplified by Electromagnetic Enhancement (through Localized Surface Plasmon Resonance LSPR) in SERS and the real time applications of SERS in our present modern world.
